php - finding the names and view of all apache environment variables -

i want know if there link of environment variables in apache , when printed out.

the reason trying write regex .htacess mod_rewrite, don't know these variables printing. it's hard write regex when im not sure printed, keep getting them wrong. there list somewhere missing.

trust me googling easier posting question , waiting response , people not quite sure asked.

i can't seem find google source.

eg %{the_request} /index.php http/1.1

the real problem having have .htaccess file

    # not remove line, otherwise mod_rewrite rules stop working  rewritebase /  options +multiviews  addhandler application/x-httpd-php .css  addhandler application/x-httpd-php .js  options +followsymlinks rewriteengine on   #nc not case sensitive #l last rule don't process futher #r 301 changes url want  rewritecond %{http_host} !^example\.host56\.com  rewriterule ^(.*)$ http://example.host56.com/$1 [r=302,l]  rewriterule ^demo(.*)$ finished$1 [nc]  rewritecond %{request_uri} / rewriterule ^(.*)$ home/$1 

i keep getting redirected error page trying to

example.host56.com/home/ 

but keeps leading me errors. home folder has index.php file inside of well

here's mod_rewrite variable cheat sheet: http://www.askapache.com/htaccess/mod_rewrite-variables-cheatsheet.html

the rule here:

rewritecond %{request_uri} / rewriterule ^(.*)$ home/$1 

is looping. reason because %{request_uri} variable always starts /, , you're not using either "^" or "$" denote matching boundaries, condition true. since it's true, rule replied. , since rewrite engine continually loops until uri stops changing (or until you've reached internal recursion limit, causing 500 error), pattern matches. try changing to:

rewritecond %{request_uri} !^/home/ rewriterule ^(.*)$ home/$1 

or

rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule ^(.*)$ home/$1
